Question

Which two points are on the graph of y = -x + 3
(-1, -2), (1, 4)
(1, 2), (0, -3)
(0, 3), (4, -1)
(4, -1), (1, 3)

Answer 1

is it C?

Answer 2

Let's check

Plug in (x,y) = (0,3). So we replace x with 0 and y with 3

y = -x + 3
3 = -0 + 3
3 = 3 ... works

Since the equation is true, this means (0,3) is on the line


Now plug in (x,y) = (4,-1). So we replace x with 4 and y with -1

y = -x + 3
-1 = -4 + 3
-1 = -1 ... works


Since the equation is true, this means (4,-1) is on the line

Answer 3

So you are correct
